Properties and Usage:
Sodium Trimetaphosphate (STMP) is used in many industries
1. Application in the food industry:
Stabilizer and emulsifier: STMP is used as a stabilizer and emulsifier in food processing, especially in dairy products and processed cheese.
Moisturizer: In meat processing, STMP is used as a humectant to help increase the juiciness and weight of meat products, maintain their freshness and flavor.
Leaving agent: As a leavening agent in baking powder, STMP enables the dough to expand fully and ensures the structural stability of baked goods.
2. Application in water treatment:
Scale inhibitor: STMP acts as a scale inhibitor in the water treatment process, preventing the formation of mineral scale in pipes and equipment, and ensuring the efficient operation of water systems.
3. Industrial applications:
Detergents and cleaning agents: STMP is widely used in detergents and cleaning agents. It not only improves the cleaning effect, but also prevents the re-deposition of dirt, ensuring that the surface is as clean as new.
Ceramic and Glass Production: In the ceramic and glass industries, STMP improves the physical properties and processing characteristics of the product, making the final product stronger and more durable.
Storage and transportation:
Store in a cool, ventilated, dry, and clean warehouse. During transportation, it is necessary to prevent rain and direct sunlight.
Packaging specifications:
25KG/Bag, or customized packaging according to customer requirements.
